23.5.2. Assumptions in Fluid Flow Analysis

Try these first

1. 1.

   What does it mean for flow to be steady?

   Hint

   Think about how velocity behaves in steady flow.

2. 2.

   Why is incompressible flow a common assumption?

   Hint

   Consider the types of fluids often analyzed in engineering.

3. 3.

   What assumption is made when fluid is treated as incompressible?

   • Density varies
   • Density remains constant
   • Velocity changes

   Hint

   Think about how liquids behave compared to gases in compression.

4. 4.

   Is Bernoulli's equation applicable near solid boundaries?

   • True
   • False

   Hint

   Consider the effects of shear stress.

5. 5.

   A fluid flows through a tube with varying diameter. Evaluate how energy changes when transitioning through narrow sections.

   Hint

   Look at how fluid velocity increases and affects pressure.

6. 6.

   A pump introduces energy to a fluid flowing through a pipe. How does this alter the application of Bernoulli’s equation?

   Hint

   What kind of energy transformation occurs with the pump?
